PP1990 Power Supply: Replacement For The DY103 Dynamotor in The ARC34

The PP1990 power supply is a replacement for the DY103 dynamotor used in the ARC34 device. It takes an input voltage range of 19-30V and provides several regulated output voltages, including +27V, +25V, +120V, +320V, and +36V. It uses transistor switching and voltage regulation to convert the input voltage to the required output voltages.
